Nitrogen cycle A simple and complete diagram of the nitrogen cycle. The blue boxes represent stores of nitrogen‚ the green writing is for processes that occur to move the nitrogen from one place to another and the red writing are all the bacteria involved. The nitrogen cycle is the process by which nitrogen is converted between its various chemical forms. This transformation can be carried out through both biological and physical processes. Important processes in the nitrogen cycle include fixation

Title: Enzyme Activity Lab Purpose: To measure the rate of enzyme activity from a tissue abstract and experiment with different factors‚ such as the enzyme solution and the substrate with different hydrogen peroxide percentages and temperature‚ that affect enzyme activity. Hypothesis: 1) If the disk is placed into each beaker with 100 units/ml of enzyme solution‚ then the time for the disk to float will be 30 seconds. 2) If the temperature of the solution is at 5 degrees Celsius‚

reaction involves enzymes. So to understand how bleach works‚ we first understand how enzymes work. Enzymes Enzymes are the most important thing in our lives‚ it makes the world go ‘round! Enzymes are proteins that acts as catalysts and help combine or break down hydrogen peroxide. Imagine a pen with ink inside it‚ when you write‚ ink comes out‚ right? You can draw‚ you can write‚ then when you finish and get your pen off of the paper‚ the ink stops coming out. Enzymes are like that‚ they

INTRODUCTION OF ENZYMES Enzymes are complex proteins that cause a specific chemical change in all parts of the body (David C. Dugdale‚ 2011). When we understand enzymes we understand cells (Marshall Brian‚ 2001). In many organisms most chemical reactions are catalyzed -when a substance speeds up the rate of a chemical reaction- by enzymes. Each enzyme controls a certain function that happens in a cell. Still each one has its own process and rate that it converts molecules. Studying enzymes shows how chemical

Enzymes are responsible for many crucial processes in living cells since they accelerate chemical reactions which would occur too slowly‚ or would lead to different products without their contribution. Enzymes are biocatalysts that usually show high affinity to a specific substrate under particular environmental conditions. The binding of the substrate and catalysis take place at a specific small region‚ around 10 amino acids‚ in the enzyme known as active site which usually represents a hydrophobic

The Carbon Cycle is a complex series of processes through which all of the carbon atoms in existence rotate. The same carbon atoms in your body today have been used in countless other molecules since time began. The wood burned just a few decades ago could have produced carbon dioxide which through photosynthesis became part of a plant. When you eat that plant‚ the same carbon from the wood which was burnt can become part of you. The carbon cycle is the great natural recycler of carbon atoms. Unfortunately
